Specification of Letters Patent.

Patented Dec. 8, 1914.

Application flled April 16, 1914. Serial No; 832,160.

To all whom it may concern:

Be it known that I, BURTON H. .Gnnon, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented a new and useful Roofing Member, of which the following is a specification.

In the production of corrugated sheet metal roofing, it is essential that the sheets be individually sufficiently rigid; that in the configuration of the sheet the surface coverable thereby be as great as possible as compared with the area of the flat sheet from which the roofing member is formed; and that the portions designed for overlapping engagement be of such character as to prevent, if possible, any leakages due to capillary action of the adjacent sheets upon the water. It is not difiicult to so form the sheet as to incorporate any two of the above-mentioned characteristics but difliculty has heretofore been experienced in incorporating in a single roofing member all of the desirable qualities above mentioned, and it is the object of my present invention to produce a rofing member having all of said qualities.

The accompanying drawing, which is a perspective vertical section, illustrates three adjacent and overlapping roofing members embodying my invention.

In the drawing, 10, indicate the roofing sheets in which the main body of the sheet is formed into a series of parallel corrugations of equal amplitude comprising valleys V and ridges R. These corrugations are of ordinary form and may, of course, be made of any desired Width preferably conforming to custom which has to a considerable extent standardized both the amplitude and width of the corrugations. It is also common practice to so corrugate the sheets that one edge of the sheet ends in a valley and the opposite edge ends in a ridge, in which case the overlapping of one sheet upon the other extends over one valley and one ridge. It is also common practice to form the sheets so that both edges are alike, in which case adjacent sheets are overlapped either one or two complete ridges.

My improvement is applicable to either form of sheet, although the drawing shows the same applied to the first-mentioned form.

My improvement resides in the deformation-of the first valley adjacent one edge of the sheet by an elevation of. the bottom of the valley so as to forman intermediate ridge 1- narrower than the other ridges and about half of the amplitude, thus forming two adjacent shallow valleys 1:, 4).. This change from standard form is accomplished without any increase in material" necessary for the formation of the sheet and without any decrease in the width of the completed sheet, so that there is no decrease in the covering area of the finished sheet, but by this change I am able to form a gutter G of sufficient size to prevent any capillary movement of any water which may leak under the edge X and travel up over the adjacent ridge of the lower sheet. It will, of course, be readily understood that some variation in form from that shown in the drawings may be had without departing from the spirit of my invention, which resides in the formation along a line parallel with the edge of the sheet of an intermediate corrugation of less amplitude than the adjacent corrugations so as to bridge over a full depth valley of a subjacent sheet.

I claim as my invention:

1. A sheet metal roofing member comprising a main body formed into a plurality of substantially parallel and equal corrugations excepting one valley between two ridges which valley is upwardly displaced to form an intermediate ridge of less amplitude than the two adjacent ridges and is flanked by two shallow valleys, substantially as shown and described.

2. A sheet metal roofing member comprising a main body having a plurality of substantially parallel corrugations forming ridges and valleys, of which two adjacent valleys beyond the first ridge at one edge are shallower than others, the ridge between said two shallower valleys being on substantially the same level as the other ridges.

A sheet metal roofing member comprising a main body having a plurality of substantially parallel corrugations fopmlng ridges and valleys, of which two ad acent valleys beyond the first ridge at one edge are shallower than others.

4. A sheet metal roofing member comprising a main body which adjacent one edge is corrugated to form a valley and a ridge farther from said edge than is said valley and adjacent the other is corrugated after the first ridge I to form three ridges with twe valleys alternating therewith the spacing between the first and third of said letter ridges being substantially double between firstnemect valley and ridtge, the valleys secend called for being shaitewer then the valley first celled fete A sheet metal reciting member eemprismain body which eetjeeent ene eflge is eerru eteci to form e valley and a ridge ferthe rem seifl the then is said vet-Hey 21115 etijeeent th v eermgeted to farm tbnee t valleys elteeneting therewith, the spacing between the first and third of said latter ridges being substen- 115 tially double that between the first-neme& valley and ridge.

In witness whereof, I have hereunto set my hand at Indianapolis, Indiana, this sev- (izty of April, A. D. one thousand! nine 20 hundred andfeurteen.
